It is taken away when being recycled gas, when to water level decreasing to lower limiting value L1, when water level declines from lower limiting value L1
It carves (L1~L2) and starts the supply that water is discharged.Then, when the supply amount that water is discharged is more than the amount of taking away, rise in water level and reach
(H1~H2) stops the supply of discharge water at the time of upper limit value H2.On the other hand, when water supply amount is discharged less than the amount of taking away,
Water level decreasing and (L1~L2) starts the supply of clear water at the time of reach lower limiting value L2.Then, rise in water level and reach the upper limit
(L1~H1) stops the supply of clear water at the time of value H1.In addition, in the case of operating condition, temperature, humidity variation, the amount of taking away
Also change with discharge water.At the moment, it can not be judged as the amount of taking away>Water is discharged, therefore supplies discharge water.Then, it is being discharged
When water supply amount is more than the amount of taking away, when water level rises and rises to upper limit value H2, stop the supply of discharge water.On the other hand,
When water supply amount is discharged less than the amount of taking away, water level decreasing.
According to such control method, supply and static control that water and clear water is discharged become simple.When only setting 1
When lower limiting value, need to judge whether only discharge water is enough, it is necessary to the amount of taking away is compared with discharge water, but be pulled away
